How To Connect - McIntosh MPI 4 Owner's Manual

3. SAW CUTOUT
Carefully cut the rectangular opening on the inside of
the pencilled rectangle.
4. SECURE MOUNTING STRIPS
Install the mounting strips (supplied in the hardware
package) on the inside of the cabinet panel. Insert
two screws (supplied in the hardware package) into
the center holes ("B" holes on the template). Use the
¾-inch long screws for panels under ½-inch thick or
1¼-inch screws for panels ½-inch thick or over. Place
a mounting strip on the back of the cabinet panel.
Align it with the three holes in the panel and tighten
the screw. The screw head should pull slightly into the
wood panel. Attach the other mounting strip by repeat-
ing the procedure.
5. MOUNT THE PANLOC BRACKETS
Attach the PANLOC brackets to the cabinet panel
using four screws of the proper length. Place the tem-
plate over the mounting screws. The screws should
be centered on the "A" and "B" holes in the template.
If necessary, loosen the screws and push the mounting
brackets into alignment then retighten.
6. INSTALL THE UNIT
Thread the power cord through the opening in the
cabinet panel. Carefully slide the instrument into the
opening so the rails on the bottom of the instrument
engage the track on the mounting brackets. Slide the
instrument in until it stops at the ad|ust position
latches. Press the latches in and continue to slide the
instrument until its front panel is flush with the cabi-
net panel. At the bottom front corners are the PANLOC
buttons. Depressing the PANLOC buttons will lock the
instrument firmly in the cabinet panel. Pressing the
PANLOC buttons a second time will release the instru-
ment You can then slide the instrument forward to the
adjust position. Pressing the adjust position latches
will allow the instrument to be removed from the
cabinet.

How to connect

The MPI 4 may be connected to a stereo receiver (Fig.
1) or to a component system with a separate preampli-
fier and power amplifier (Fig. 2). Choose which most
closely resembles your system.
AUDIO INPUTS
Low Level Audio Input
Use one of the 6-foot shielded cables supplied, to con-
nect the left channel output on your preamplifier to the
LEFT AUDIO INPUT on the MPI 4 back panel. Similarly,
connect the right channel preamplifier output to the
RIGHT AUDIO INPUT.
SPEAKER INPUT
There are four color-coded push connectors on the back
panel of the MPI 4. Connect these with two pairs of speaker
cables to the left and right output on the power ampli-
fier.
Black Left speaker common terminal
Green Left speaker high terminal
White Right speaker common terminal
Red Right speaker high terminal
Set the SPEAKER IMPEDANCE switch on the MPI 4 back
panel to agree with the speaker system impedance: 4W,
8W, or 16W.
TUNER INPUTS
Signal Strength Input
Mclntosh tuners and receivers provide signal for the
SIGNAL STRENGTH INPUT at a connector marked TP 1
on the back of each tuner. Using the 3-foot low-capacity
shielded cable supplied, connect the TP 1 output to the
SIGNAL STRENGTH INPUT.
TO PREVENT HIGH FREQUENCY LOSSES, THE SPECIAL
3-FOOT CABLES SUPPLIED MUST BE USED. DO NOT
SUBSTITUTE O R D I N A R Y AUDIO CABLE.
For other tuners or receivers which do not provide a
signal strength output, consult the manufacturer or their
authorized service agency.
Deviation Input
Mclntosh tuners and receivers provide signal for the
DEVIATION INPUT at a connector marked TP 2 on the back
of each tuner. Using the 3-foot low-capacity shielded
cable supplied, connect the TP 2 output to the DEVIA-
TION INPUT.
TO PREVENT HIGH FREQUENCY LOSSES, THE SPECIAL
3-FOOT CABLES SUPPLIED MUST BE USED. DO NOT
SUBSTITUTE O R D I N A R Y AUDIO CABLE.
For tuners or receivers which do not provide a devia-
tion output, consult the manufacture or their authorized
